HELP (!) Left My Windows OPEN in Heavy Rain...!!!

[Pacquiao]

It was blazing hot this afternoon, so I left all the windows open at about 2.5 inches. Then we took my girlfriend's car to a restaurant that was 45 minutes away. It rained hard for about 15 minutes straight according to my roommate... When I got back, it had stopped raining. The window gauges were soaked, so I wiped them up very quickly and tested them. They're fine. Shockingly, the carpeting and seats were only slightly damp. I lifted the floor mats and it wasn't wet underneath at all. So questions:

- the window switches probably took the biggest hit... does anyone know if they drain somewhere? Like drain holes?

- is there any risk of mildew/rotting?

It's mostly sunny at 89 degrees tomorrow, so I'm gonna lower my windows while I am at work and let that shit sit in the sun. Hope my Yaris isn't ruined.
